Audibax Pro Manhattan 18S - 18″ active subwoofer, 1800 W RMS, 142 dB peak with DSP and XLR output

The Audibax Pro Manhattan 18S is a high-performance professional active subwoofer with an 18″ woofer and 4″ voice coil , designed to provide deep, controlled bass in modern PA systems. Its Class D power amplifier delivers 1800 W RMS (up to 3600 W peak ), with a frequency response of 35 Hz to 150 Hz , sensitivity of 97 dB (1 W/1 m) and maximum SPL of up to 142 dB (peak) . It integrates DSP with CAN BUS network for adjustment and monitoring, including tools such as a low-pass filter and a 6-band parametric equalizer to adapt the system to the room. Connectivity is direct: XLR/Jack combo input and XLR line output to chain speakers or send the signal to other amplifiers. It incorporates a masthead socket (stand) and a multi-layer laminated wood enclosure that maximizes rigidity and minimizes resonances.

The 18S is part of the Manhattan series , alongside the 10″, 12″ and 15″ active models, designed for DJs, musicians and sound companies that require robust solutions ready for touring or permanent installation.
